Polyaromatic hydrocarbons PAHs - Anthracene in sediment results HOLAS 3

This core indicator evaluates the status of the marine environment based on concentrations of polyaromatic hydrocarbons PAHs - Anthracene in sediment. Quantitative thresholds are used to evaluate if core indicators status is "Achieve", "Fail" or "Not assessed". Attribute specifications and units: "HELCOM_ID" = Code of the HELCOM scale 4 assessment unit "country": country in which the HELCOM assessment unit is located or a mention to an open sea area "level_2" = Name of the HELCOM assessment unit in scale 2 "Name" = Name of the HELCOM assessment unit in scale 4 "Open_sea" = Name of the HELCOM assessment unit in the open sea "F2_Name" = Name of the HELCOM assessment unit "determinan" = Determinat "est" = The estimated mean loge concentration in the assessment unit "se" = The standard error on the estimated mean log concentration in the assessment unit "fit" = The estimated mean concentration in the assessment unit "upper_cl" = Upper one-sided 95% confidence limit on the mean concentration: exp(est + qnorm(0.95) * see) "colour" = symbology "Status" = Overall Status of the indicator according to one-out-all-out本核心指标以沉积物中多环芳烃（Polyaromatic Hydrocarbons, PAHs）-蒽（Anthracene）的浓度为依据，评估海洋环境状况。通过定量阈值判定该核心指标的状态为"达标"、"不达标"或"未评估"。 属性说明与单位： "HELCOM_ID"：HELCOM四级评估单元的编码 "country"：HELCOM评估单元所在国家，或公海区域的指代名称 "level_2"：HELCOM二级评估单元的名称 "Name"：HELCOM四级评估单元的名称 "Open_sea"：HELCOM公海评估单元的名称 "F2_Name"：HELCOM评估单元的名称 "determinan"：测定指标 "est"：评估单元内的对数浓度均值估计值 "se"：评估单元内对数浓度均值估计值的标准误 "fit"：评估单元内的浓度均值估计值 "upper_cl"：浓度均值的单侧95%置信上限：exp(est + qnorm(0.95) × se) "colour"：符号样式 "Status"：依据"一票否决"原则确定的该指标整体状态
